F060M01A-AAT o Engine Oil and Filter The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the car is being driven in severe conditions,more frequent oil and filter changes are required. F060B01A-AAT
o Drive Belts Inspect all drive belts for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. Drive belts should be checked periodi-cally for proper tension and adjusted as necessary. F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at
which the vehicle may be driven, dam-age the emission system and cause hard starting. If an excessive amountof foreign matter accumulates in the fuel tank, the filter may require re- placement more frequently. After installing a new filter, run the
engine for several minutes, and checkfor leaks at the connections. Fuel fil- ters should be installed by trained technicians. WARNING (Diesel only):
Never work on injection system with engine running or within 30 sec- onds after shutting off engine. Highpressure pump, rail, injectors and high pressure pipes are subject to high pressure even after the enginestopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People usingpacemakers should not move than 30cm closer to the ECU or wiring harness within the engine roomwhile engine is running, since the high currents in the Common Rail system produce considerable mag-netic fields.

o Fuel Lines, Fuel Hoses and Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.Replace any damaged or leaking partsimmediately.

6CHECKING THE ENGINE OIL
G030A02O-GAT
Recommended Oil Gasoline Engine Engine oil is essential to the perfor- mance and service of the engine. It is suggested that you check the oil level at least once a week in normal useand more often if you are on a trip or driving in severe conditions. The engine oil quality should meet the following classification. API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE G030B01JMNOTE:
o For good fuel economy, SAE 5W-20 (5W-30), ILSAC GF-3 en-gine oil is preferred regardless of regional option and engine variation.
o If SAE 5W-20, ILSAC GF-3 en- gine oil is not available, second-ary recommended engine oil forcorresponding temperature range can be used.

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of
lubricating and cooling the inside of the engine. Engine oil consumption
It is normal that an engine should
consume some engine oil while nor- mal driving. The cause of oil con- sumption in a normal engine are asfollows;
o Engine oil is used to lubricate pis- tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of the oil into the combustion cham- ber.This oil with some oil of the cylin-der wall is burned by the high tem-perature combustion gases during the combustion process. o The engine oil consumption is
strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition.
1. Remove the oil filler cap by turning
it counter-clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clock- wise.
The distance between the "F" and "L"marks is equal to about 1 liter(GasolineEngine)/1.2 liter(Diesel Engine) of oil.

CAUTION:
Slowly pour the recommended oil using by a funnel. Do not overfillnot to damage engine.
!
NOTE: Always dispose of used engine oil in an environmentally acceptablemanner. It is suggested that it be placed in a sealed container and taken to a service station for maybereclaimation. Do not pour the oil on the ground or put it in with the household trash.
Be sure that the mounting surfaceon the engine is clean and that theold gasket is removed completely. Lubricate the new gasket on the filter with clean engine oil beforeinstallation.
7. Remove the engine oil level dip- stick.
8. Refill the crankcase with the rec-
ommended engine oil. Refer tothe specification in chapter 9 for engine oil capacity.
!
9. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
10.Shut off the engine and recheck the oil level. WARNING:
Used motor oil may cause irrita-
tion or cancer of the skin if left in contact with the skin for prolongedperiods of time. Wash your hands thoroughly with soap and warm water as soon as possible afterhandling used oil. G040B04FC-GAT

Use a high quality ethylene-glycol
coolant in a 50/50 mix with water.
10.Start the engine and check to be
sure no oil is leaking from thedrain plug or oil filter.
11.Shut off the engine and recheck
the oil level.
NOTE:
o It is recommended that the en- gine oil and filter should be changed by an authorized Hyundai dealer.
o Always dispose of used engine oil in an environmentally accept-able manner. It is suggested that it be placed in a sealed container and taken to a service station formaybe reclaimation. Do not pour the oil on the ground or put it into the household trash.
WARNING:
Used motor oil may cause irrita- tion or cancer of the skin if left in contact with the skin for prolongedperiods of time. Wash your hands thoroughly with soap and warm water as soon as possible afterhandling used oil.

The engine coolant should be com- patible with aluminum engine parts.Additional corrosion inhibitors or addi- tives should not be used. The cooling system must be maintained with thecorrect concentration and type of en- gine coolant to prevent freezing and corrosion. Never allow the concentra-tion of antifreeze to exceed the 60% level or go below the 35% level, or damage to the cooling system mayresult. For proper concentration when adding or replacing the engine cool- ant, refer to the following table. G050C01A-GAT
To Check the Coolant Level The level of the coolant should bebetween the "L" and "F" lines on thereservoir when the engine is cold. If the level is below the "L" mark, add engine coolant to bring it up between"L" and "F". If the level is low, inspect for coolant leaks and recheck the fluid level frequently. If the level dropsagain, visit your Hyundai dealer for an inspection and diagnosis of the rea- son.

CHECKING THE BRAKES
G120A01A-AAT
! CAUTION:
Because brakes are essential to
the safe operation of the car, it is suggested that they be checked and inspected by your Hyundai dealer. The brakes should bechecked and inspected for wear at those intervals specified in the vehicle maintenance schedule inSection 5.
WARNING (Diesel only):
Never work on injection system
with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec-tors and high pressure pipes are subject to high pressure even af- ter the engine stopped. The fuel jetproduced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers shouldnot move than 30cm closer to the ECU or wiring harness within the engine room while engine is run-ning, since the high currents in the Common Rail system produce considerable magnetic fields.
WARNING:
The cooling fan is controlled byengine coolant temperature andmay sometimes operate even when the engine is not running. Use extreme caution when workingnear the blades of the cooling fan, so that you are not injured by a rotating fan blade. As the enginecoolant temperature decreases, the fan will automatically shut off. This is a normal condition.Fluid level should be within this range
3. If the transaxle fluid level is low, use a funnel to add transaxle fluid through the dipstick tube until the level reaches the "HOT" range. Do not overfill. C090A03FC
